Bottom steering head yolk CB500/4 K1

(1/5) > >>

flatfour:
Does anyone have a bottom fork yolk for a CB500 K1 that they are willing to part with? I took my 500 for MOT today and the tester noticed that one of the lock stops is bent on the lower yolk.

He has passed the bike anyway (it is the same dealership that I have used every time since buying the bike in 2003) but advised that it is replaced. I have checked on the DS and CMSNL sites, however neither has this part.

I believe that this problem must have been there since before I bought the bike, as nothing has happened to it whilst I have owned it. It is only noticeable because the handlebars are closer to the tank on a full right - hand lock than on a full left - hand lock. A check of the lock stops then shows that the left side is slightly bent back, whereas the right side is straight.

I have been told that the dangers of heating it up and trying to straighten it are too great to make the exercise worthwhile, as it is cast and likely to break.

Many thanks in advance for any help that is available.

Trigger:
This is common on all old bikes. You can just get it welded  ;)

MCTID:
I agree with Trig.....get it welded........a good Welder will have no problem with it and you can grind it back to the profile you want quite easily.....just measure it up and determine the finished profile before you strip the Yoke/ forks etc.

Many thanks for the advice, I will wait until the riding season has ended and then take it to our aero engineer, who is a CAA approved welder and seems to be able to weld almost anything.

Bryanj:
The reason its bent is that somebody at some time has fallen off and the handlebars have been pushed round bending the lug, carefull if you try to straighten it as they usually break off but teh bit cn be easily welded back on---it aint aero science
